Window STC Rating: 27 or better using 1/8 inch (3.18 mm) double strength glass. C. Unitary Windows: 1. Install so as not to affect the exterior architectural features of existing windows. 2. Must provide improved energy conservation, ease of cleaning, reduced condensation, and noise reduction. 3. Must be easily removable without the use of tools. 4. Double Hung Interior Storm Windows: To be made to match, meeting rail height of existing windows. Both sashes to be operable. Double track at sides and top only. D. Compression Windows: To be of unitary type, not requiring separately installed track or attachment hardware to either sides or bottom of existing openings. E. Unitary Frames: 1. Capable of self-adjusting to any irregularity or out-of-square condition in existing openings. 2. Must provide a positive force on existing opening to effect a compression seal of weather-stripping. 3. A permanently mounted guide channel may be used at the top of existing opening for positioning and security. F. A permanently mounted guide channel may be used at the top of existing opening for positioning and security. 1. Not requiring separately installed track or attachment hardware to either sides or bottom of existing openings. G. Corners: Mitered and screwed. H. To match meeting rail height of existing windows. Both sashes to be operable. Double track at sides and top only. I. Measurements: For ordering windows. 1. Equipment: a. Tape Measure: Locking. 3 inch (76 mm) Case. b. Framing Square: 16 x 24 inches (406 x 610 mm). To check squareness. c. Ruler: 6 or 12 inch (152 to 305 mm) ruler. d. Manufacturer's Window Worksheet to record measurements. 2. Measure all 4 sides to 1/16 inch (1.5 mm) and record the actual measurement. a. Do not average. b. Don't bend the tape into the corner. Add the tape case dimension to your measurement. c. Measure exactly where the window will be mounted. 3. Check for Out of Square: Notice the framing squares at the left and right bottom corners and the 2 lines under each framing square where you record the gap on the worksheet. a. Start tight to the left side and slide the 24 inch (610 mm) side down until it touches the sill at either the corner or the end. b. Hold the framing square tight against the side so any gap will show up at the bottom. c. If the window is square at the bottom, you would record a "0" at each of the 4 lines under the framing squares. If the gap is 1/16 inch (1.5 mm) or less it is effectively square. d. Place the framing square against the right side of the window and repeat the procedure. Think of this as a snapshot of each bottom corner. In reality, they overlap, but for clarity they are separated and are not to scale. e. Next, lay the 24 inch (610 mm) side of the framing square on the sill to check if the sill is bowed up or down, if so give us a center vertical measurement and draw an arc showing the bow. 4. Windows accommodate 3/16 inch (5 mm) vertical and 1/2 inch (13 mm) horizontal play. a. Deep Openings: Measure where you want the window to be and measure the opening at the wall to check that it does not get smaller than these tolerances. 1) Contact manufacturer if the opening is smaller or the bottom of the opening is obstructed. 5. Double Hung Storm or Large Opening as Mullion Separated Upper and Lower Windows: a. Measure from the sill to the top of the meeting rail, where the dust collects. 1) This is where the top of the mullion will be. b. A window opening may be done as one window or two windows with a mullion. 6. Double Hung Windows 72 inches (1829 mm) or Taller: Should be done as 2 windows with a horizontal mullion. a. Measure the length for the mullion where it is to be installed. b. Vertical Mullions: Vinyl covered wood. 1) Depth: 1-5/8 inch (41 mm). Width: 1-1/8 inch (28 mm). 2) Vinyl Color: Is to match the window. c. Horizontal Mullions: Measure the width and height of the entire opening. 1) Thickness: 3/4 inch (19 mm). Width: 1 inch (25 mm). 2.3 INTERIOR MOUNTED REMOVABLE STORM WINDOWS A. Glazing: ** NOTE TO SPECIFIER ** Delete glazing options not required. 1/8 inch is standard.
